So you have 3 branches in your /aufs_vertex. - /aufs_dynamic, rw, tmpfs - /aufs_vertex/mnt/aufs/overlay, rw, ?? - /aufs_vertex/mnt/aufs/images/10-desktop.squash, rr, squashfs If you can, please try again without /aufs_vertex/mnt/aufs/overlay, eg. /aufs_vertex = /aufs_dynamic(rw,tmpfs) + /.../10-desktop.squash(rr,squashfs) And run several commands and any version of kde. With these 2 branches, pdflush will not eat your cpu, I hope. And then, - mount /aufs_vertex/mnt/aufs/overlay - write several things to it directly, eg. no aufs - "find /aufs_vertex/mnt/aufs/overlay -ls > /dev/null" repeatedly in background may be good - and see what will happen to pdflush. In /aufs_vertex/mnt/aufs/overlay standalone, pdflush MAY eat your cpu up. I just want you to make sure. > But when i start any kde4 application my cpu becomes busy and top shows pdf= > lush = > > with about 99% usage. I've no idea how to debug this.

So your good case is - linux kernel 2.6.2?? - aufs1, last version - kde3.5 and kde4 and bad case is, - linux-2.6.29 - aufs2 - kde4 Am I right? J. R.
